I'd like to get lilypond to produce the ://: mark above the stave used in hymnals (at least) to indicate "repeat the preceding line of words here" - for an example of what I mean, see the mark above the stave in the first bar of the second page. Is it possible? I've spent some time looking a snippets to no avail - it doesn't appear to be a glyph I could include using \markup or anything like that...
I found a hack, which is to use the closest-approximate unicode glyph as a breath mark:
\override BreathingSign.text = "𝄏"
\breathe
\repeat percent 2 { c'1 c' }
. The name of the Lilypond's internal symbol isDoublePercentEvent
. You will find basic information here: lilypond.org/doc/v2.21/Documentation/notation/… . Maybe someone knows how to use that symbol in a markup.
